FRONT PANEL FUNCTIONS NOTES
11. PRESENCE

content in your sound. Turn clockwise
to add bite for a more cutting tone.
PRESENCE is an power-stage function
and acts independently of the preamp
EQ network.
12. RESONANCE
Controls the amount of lower frequency
content in your sound. Turning this
control clockwise adds a resonant
bass boost, increasing bottom end.
RESONANCE is a power-stage function
and acts independently of the preamp
EQ network.
13. REVERB

14. OUTPUT
This three position rocker switch
combines STB (standby) and HIGH/
LOW output power functions. The
output stage and power control for this
amplier has been designed to deliver
the optimum tonal performance at
all power levels. The HIGH and LOW
output functions allow the user to
choose between two congurations of
the internal power supply. These two
congurations give the choice between
two output power levels, but ensure that
the output valves behave in the same
way for both. This means the amplier
can be put into LOW power mode
without compromising on tone.
HIGH: This is the 20 Watt high power
setting.
STB (standby): This is used in conjunction
with the mains POWER switch (Front Panel
Function #15). When powering up, always
switch mains POWER on rst, leaving
the OUTPUT switch in the STB (standby)
position. Standby mode should also be
used to mute the amp during breaks in
performances to avoid stress to the valves
of the amplier.
LOW: This is the 10 Watt low power setting.
15. POWER
Mains power switch.
